System Capacity - System Load

The first four graphs on the System Capacity window show the system load reports. These reports show the overall CPU usage on the appliances. AsyncOS is optimized to use idle CPU resources to improve transaction throughput. High CPU usage may not indicate a system capacity problem. If the high CPU usage is coupled with consistent, high-volume memory page swapping, you may have a capacity problem. This page also shows a graph that displays the amount of CPU used by different functions, including processing for the Web Security appliance reporting. The CPU-by-function graph is an indicator of which areas of the product use the most resources on your system. If you need to optimize your appliance, this graph can help you determine which functions may need to be tuned or disabled.

Additionally, the Response Time/Latency and Transactions Per Second graphs shows the overall response time (in milliseconds), and transactions per second for the date range specified in the Time Range drop-down menu.
